Study Notes
Simplifying Radical Expressions
- To simplify radical expressions with numerical and variable radicands, operations such as adding, subtracting, multiplying, and dividing can be used.
Rationalizing the Denominator
- The process of rationalizing the denominator of a radical expression involves multiplying the numerator and denominator by the conjugate of the denominator to eliminate the radical from the denominator.
Permissible Values for Radical Expressions
- A permissible value for a radical expression is a non-negative real number.
Solving Radical Equations Algebraically
- The process of solving a radical equation algebraically involves isolating the radical on one side of the equation, then squaring both sides to eliminate the radical, and finally solving the resulting equation.
Extraneous Roots in Radical Equations
- Extraneous roots occur when solving radical equations because the squaring process introduces new solutions that are not part of the original equation.
